    Default 640X480 Screen

    I have a problem with my screen resolution.
    I can get nothing higher than 640X480.
    I have had Opensuse 11.4 installed for a while now (from a fresh install) and it has been working without any problems. But tonight, all I can get is a max resolution of 640X480.
    I have tried rebooting... no change. The splash screen when booting is normal, but the login screen and after is low rez.
    teh output of xrandr is
    Code:
    xrandr: Failed to get size of gamma for output default
    Screen 0: minimum 320 x 175, current 640 x 480, maximum 640 x 480
    default connected 640x480+0+0 0mm x 0mm
       640x480        50.0*    51.0     52.0     53.0     54.0     55.0  
       640x400        56.0  
       640x350        57.0  
       576x432        58.0  
       512x384        59.0     60.0     61.0     62.0     63.0  
       416x312        64.0  
       400x300        65.0     66.0     67.0     68.0     69.0  
       360x200        70.0  
       320x240        71.0     72.0     73.0     74.0  
       320x200        75.0  
       320x175        76.0
    I have tried
    Code:
     cvt 1680 1050
    in the terminal,
    but that didn't do anything
    I also copy/pasted the output of cvt 1680 1050 into the "50-monitor.conf" file.

    What am I doing wrong here? I did install a few updates between working and not working. They were the "bootsplash, openvpn and yast2-control-center" updates.

    My system is OpenSuse 11.4_64
    KDE 4.6.0 release 6
    Nvidia GeForce 8600 GTS
    NVIDIA 260.19.44 driver.

    I have looked at the nvidia x server settings. It also has the highest resolution as 640x480.

    Anyone got any ideas?
    Thanks

    OpenSuse 11.4 or CloseSuse 11.4? Simply not working with my monitor. I am writing this comment using Xubuntu, a smarter mice, not doubt about it.

    Why releasing a new version of Opensuse without even testing it?

    No more comments....

    Is there a way to roll back the last lot of updates to see if they are the problem?

    I'm at work, so I can't check my computer at the moment. Will I be able to reinstall the older versions of the files that were updated?
    Will this have to be done manually or is there a way to automatically reinstall the previous versions?

    I'm using the digital input on the monitor, would it be worth trying the VGA?
    Thanks

    You can usually install the older version. But I suspect this is not the problem. By all means get the list of packages that you think are involved, everything there is dated, so the last changes are right at the end of the file.

    The graphics card you have should not even need any config files, I never do anything but install the driver like this
    nVidia Driver via Repo in 11.3 & 11.4 - Guide

    I'd be interested to know if the boot options at the grub boot menu has changed?

    What should the boot option be?
    I have had it boot into text mode by typing 3 (I think) when grub boots. Is there an option for a higher resolution?

    No you are reading me wrong. I was suspecting that a new kernel had been dragged in with some of your updates/package installs. I have seen before where a new install starts life from kernel-desktop, the user starts installing all and sundry and a new kernel like kernel-default is added and takes priority. Only trouble is, the graphics driver is installed to kernel-desktop. (Are you following)

    So what I mean is, are there more boot options in the menu, not have the kernel arguments changed.

    The vga entry in my kernel arguments is: vga=0x31a, I have nomodeset added as well of course

    Ahh, O.k. Would reinstalling the graphics driver again help?
    (I'm trying to follow)

    I'm just about to go home, I'll have a look at the boot menu. I don't think there are any new entries.
    I'll post back soon.

    If there are no new entries then I would look at the install history, it may tell you something.
    But if you have added any xorg config files I would remove them
    Check the /boot/grub/menu.lst has not been modified from your original working file
    Check your settings against my guide quoted in post #6
